Convert weights
This app converts between stones, pounds, ounces, kilograms, grams, cups (American cooking measure of volume). It has been uploaded to Amazon apps store. It uses radio buttons, and various rounding and formatting, as well as text (numeric) input and output.
app/res/drawable - (pictures) - nothing in here
app/res/mipmap/ic_launcher.png/ - icon for launching app
An image called ic_launcher.png is moved into all 5 versions of ic_launcher.png. It involves overwriting what's there already.
